Type material. Holotype: ♂ (MHBU-ARA-00023644), CHINA: Hunan Province, Chenzhou City, Yizhang County, Mt. Mangshan , Jiangjunzhai , 24.9511°N, 112.9288°E, 1192 m elev., 14 November 2020, leg. K. Yu, Y. Mu & S. Zhang, HBUARA#2020-46 GoogleMaps . Paratypes: 2♂ 3♀ (MHBU-ARA-00023645~MHBU-ARA-00023646), same data as holotype GoogleMaps .

Etymology. The specific epithet is in honor of Mr. Shuyuan Zhang (Shanghai), a spider lover who has given tremendous help to the first author in collecting specimens.

Diagnosis. It resembles O. jinping sp. nov. in the shape of embolus, but can be distinguished by the ridge near embolic base that is pointing downwards ( Fig. 229 View FIGURES 229–232 ; vs. pointing upwards in O. jinping sp. nov.). Females can be distinguished from O. jinping sp. nov. by the short and thick accessory glands ( Fig. 232 View FIGURES 229–232 ; vs. AG is slender in O. jinping sp. nov.).

Description. Male. Habitus as shown in Fig. 222 View FIGURES 222–228 . Measurements of holotype: carapace length 2.73; abdomen length 2.76; measurements of eyes: AME 0.50, ALE 0.31, PME 0.06, PLE 0.21; measurements of legs: I 5.53 (1.65, 1.02, 1.34, 0.95, 0.57), II 4.31 (1.33, 0.83, 0.85, 0.77, 0.53), III 4.36 (1.37, 0.71, 0.83, 0.86, 0.59), IV 4.82 (1.45, 0.72, 1.10, 1.03, 0.52); leg formula 1432. Carapace dark, cephalon covered by relatively dense yellow setae; dorsal abdomen with four interrupted longitudinal yellow setal bands. Melanic areas on legs I–II more obvious than III–IV.

Palp ( Figs 224–226 View FIGURES 222–228 ): palpal bulb swollen, lobe-like protrusion of tegulum short and stout; embolus relatively slender, curved in ventral view, with one ridge near embolic base pointing downwards ( Fig. 229 View FIGURES 229–232 ); apophysis on embolic disc sharp ( Fig. 229 View FIGURES 229–232 ); RTA wide at basal and median part, distal part gradually narrow; ventral femoral bump relatively low, triangular ( Fig. 226 View FIGURES 222–228 ).

Female. Habitus as shown in Fig. 223 View FIGURES 222–228 . Measurements of paratype: carapace length 2.28; abdomen length 2.67; measurements of eyes: AME 0.39, ALE 0.27, PME 0.06, PLE 0.19; measurements of legs: I 3.74 (1.16, 0.77, 0.76, 0.57, 0.48), II 3.33 (1.08, 0.66, 0.62, 0.53, 0.44), III 3.68 (1.22, 0.63, 0.67, 0.70, 0.46), IV 4.26 (1.31, 0.66, 0.94, 0.87, 0.48); leg formula 4132. Coloration like male but legs lighter, setae on dorsal body sparse .

Epigynum ( Fig. 227 View FIGURES 222–228 ): atria oval and small, close to each other and far away from genital furrow. Vulva ( Fig. 228 View FIGURES 222–228 ): starting part of copulatory ducts enlarged and fused to spermathecae; accessory glands short, chimney-shaped; spermathecae dark, strongly sclerotized.

Natural History. All specimens were collected under bark of tree trunk.

Distribution. China (Hunan).
